Re: ZR-1 Delivery locations
I would love to find a little more history about mine. It was brought over to Australia in 2000 and converted to RHD in 2001. Conversion and compliance took over a year.

Hi all, bit un-related to the topic. How does the 94 + dash compare to the early years in terms of quality? Does it actually feel cheaper? I have only seen my 1990 here in Australia. I would have...

Re: Injector issue with 1990?
Oh right, I assumed the LT5 used a similar distributor to the LT1.

Re: Injector issue with 1990?

I totally stand by Marc's chip as well and believe he tuned the car as to what I supplied him.
Correct me if I am wrong, but the tuning on his chip eliminates any tuning done to the...
